- Factory menu item: Other Setting->AUDIO Curve Setting, for sound curve adjustment; if without special customer requirements, the item need not adjustment commonly for it has been preset by software;
Note: If software is upgraded or there
have been date in EEPROM
already, please
execute item “RESET
ALL” to clear out
all data before adjustment for the first time.
ADC CALIBRATION OF VGA
- Switch “source” to VGA channel;
- Press key “SOURCE”, then press keys “2, 5, 8, 0” in turn to enter into initial factory menu;
- Move cursor to item “ADC ADJUST” and press key “OK” to enter into inferior factory menu;
- Input VGA signal VG848: Timing 856 1024×768/60 Hz, Pattern 920 Gray 8 step(H); move cursor to item “MODE ”press keys “UP” and “DN” to select item “RGB” then move cursor to item “AUTO ADC” and press key “OK” to begin auto-adjustment until completing the calibration.
ADC CALIBRATION OF YPbPr
- Switch “source” to YPbPr channel;
- Press key “SOURCE”, then press keys “2, 5, 8, 0” in turn to enter into initial factory menu;
- Move cursor to item “ADC ADJUST” and press key “OK” to enter into inferior factory menu;
- Input Y/Pb/Pr signal VG848 Timing 976 720P, Pattern 918 SMPTE Color Bar; move cursor to item “MODE ” press keys “UP” and “DN” to select item “YPbPr” then move cursor to item “AUTO ADC” and press key “ENTER” to begin auto-adjustment until completing the calibration, prompt “SUCCESS” displaying below “AUTO ADC” means successful auto-calibration.
WHITE BALANCE ADJUSTMENT
- Unless specified by customer, default color temperature “COOL” is 12000K and its chromatic coordinates is (272, 278); color temperature “NORMAL” is 9300K and its chromatic coordinates is (285, 293); color temperature “WARM” is 6500K and its chromatic coordinates is (323, 329);
- TV set should be working over 30 mins to be in stabler state before white balance adjustment; Use white balance apparatus CA210 and switch to its BBY channel.
- Switch “source” to HDMI channel;
- Press key “SOURCE”, then press keys “2, 5, 8, 0” in turn to enter into initial factory menu;
- Move cursor to item “W/B ADJUST” and press key “OK” to enter into inferior factory menu;
- Input DVI/HDMI signal (16 Gray Scale Signal: 1024×768/60Hz, TIMING: 856, PATTERN:921); move cursor to item “MODE”, press keys “UP” and “DN” to select item
- “HDMI1” or other HDMI channels, then move cursor to item “TEMPERATURE” and press keys “UP” and “DN” to select item “COOL”;
- Adjust items “R-GAIN, G-GAIN, B-GAIN” to set chromatic coordinates of 14th scale as (272, 278);
- Adjust items “R-OFFSET, G-OFFSET, B-OFFSET” to set chromatic coordinates of 4th scale as (272, 278);
- During adjustment, make sure that chromatic coordinates of bright scale are (X=272±10, Y=278±10) and chromatic coordinates of dark scale are (X=272±10, Y=278±10);
- Move cursor to item “COPY ALL” again to copy data of white balance to other channels except DTV;
- Check if chromatic coordinates of HDMI NORMAL and WARM meet the requirements of error allowance (dark scale: ±10, bright scale: ±10) or not, otherwise adjust items “R_GAIN/B_GAIN/R_OFF/B_OFF” to meet them and then save the data; 10) Switch to other channels (ATV, AV-COMPONENT-D-SUB), check if chromatic coordinates of COOL, NORMAL and WARM meet the requirements or not, if not, adjust them respectively in the same way of HDMI and with 16 gray scale signal; exit menu “W/B ADJUST” after adjustment, the data will be save automatically.
DTV ADJUSTMENT
Switch to DTV channel, select 16 gray scale program,
enter into factory menu.
- B Gun: coordinates of X and Y will increase when B gun is adjusted downwards; coordinates of X and Y will decrease when B gun is adjusted upwards;
- R Gun: adjusting R gun will effect coordinate of X, and value of Lv slightly; coordinate of X will increase when R gun is adjusted upwards; coordinate of X will decrease when R gun is adjusted downwards;
- G Gun: adjusting G gun will effect coordinate of Y, and value of Lv greatly; coordinate of Y will increase when G gun is adjusted upwards; coordinate of Y will decrease when G gun is adjusted downwards.
Default color temperature specified by SANYO customer is Normal, adjust chromatic coordinates of Normal and Cool in Dynamic picture mode; adjust chromatic coordinates of Cool in Dynamic picture mode for other customers.
FUNCTIONS CHECKUP [TV FUNCTIONS]
- Input central signal to RF port, enter into menu “CHANNEL” first, then search channels automatically, check if there is any omitted channel, check if the output of speakers and the picture are normal.
AV PORT
- Input signal to AV port respectively, check if the picture and the sound are normal
YPbPR / YCbCr port
- Input YUV signal from VG848 signal generator with YUV formats listed as Table 3 respectively, check if the picture and the sound are normal under the circumstances of power-on/off, switching channel and format, etc
